feat: dynamic directory playlists via [[dir]] sources - #308
Conversation
Playlists can now reference directories with [[dir]] sections instead of listing every track. Directory sources are scanned at load time, so new files appear and removed files disappear automatically. - parsePlaylistDoc keeps explicit tracks and dir sources in document order - expand resolves dirs into tracks, marking them DirSourced; explicit [[track]] entries always shadow a directory scan of the same path - savePlaylist preserves [[dir]] sections and skips DirSourced tracks - bookmarking a dir-sourced track materializes it as an explicit entry so the bookmark persists - RemoveTrack refuses dir-sourced tracks; AddTracks dedupes against them - Playlists()/SearchTracks operate on the expanded view - CreateDirPlaylist, AddDirSource (deduped), DirSources added
playlist create and add accept repeatable --dir flags that reference a directory as a [[dir]] source, and a new 'playlist dirs' subcommand lists them. --dir cannot be combined with --ssh. enrich skips dir-sourced tracks and sort notes that they reload in scan order.

In `@cmd/playlist.go`:
- Around line 75-77: Update PlaylistCreate and PlaylistAdd to resolve and
validate every input, including explicit audio paths and all directory sources,
before any playlist mutation. Add a provider operation that validates and
persists the complete directory-source set atomically, and route both commands
through it so failures in path resolution or later sources leave no partial
playlist or source updates. Add regression coverage for mixed inputs that fail
after validation begins.
- Around line 538-540: Preserve the original [[track]]/[[dir]] section order on
every playlist rewrite. In cmd/playlist.go lines 538-540, update bookmark
materialization to retain each section’s original position; in cmd/playlist.go

regrouping sections; and in ui/model/keys.go lines 2257-2264, persist reorders
while retaining directory-section placement and applying order changes only to
supported explicit tracks.
- Around line 161-172: Update the directory-addition flow around AddDirSource to
store the dir value whenever an addition succeeds, then use that stored
successful directory in the addedDirs == 1 message instead of dirs[0]. Preserve
the existing messages for zero and multiple additions.
In `@commands.go`:
- Around line 459-469: Update site/index.html to document the playlist directory
options: playlist create --dir, playlist add --dir, and playlist dirs. Match the
existing documentation structure and wording used in docs/, without changing the
command implementations.
In `@external/local/provider.go`:
- Around line 264-300: Wrap errors returned by the directory playlist operations
with contextual fmt.Errorf(... %w ...) messages: update CreateDirPlaylist for
MkdirAll, safePath, OpenFile, and Close, and apply the same treatment to the
corresponding failure paths in AddDirSource and saveDoc. Preserve existing
error-specific handling while making each message identify the failed operation.
- Around line 370-394: Update saveDoc to render the complete document into an
in-memory strings.Builder before creating or renaming the temporary file, then
write the rendered content and validate the write before the atomic rename.
Change writeTrack to accept an io.Writer, matching writeDir, and preserve the
existing doc.order traversal and cleanup behavior on any rendering or file-write
failure.
In `@resolve/resolve.go`:
- Around line 306-366: Update AudioFiles to perform the shared os.Stat and
single-file supported-extension handling once before branching on recursive. In
the recursive filepath.WalkDir callback, skip entries that provide a traversal
error instead of returning that error, while continuing to collect readable
supported audio files and sort the results; preserve the existing error behavior

If no matching track remains, return before persisting; otherwise remove the
matched saved entry and preserve the existing directory-source protection.

A track added from a directory-backed playlist carried its DirSourced flag into the destination playlist. savePlaylist then dropped it (the destination has no owning [[dir]] section), so the track was reported as added but silently lost. Clear the flag on incoming tracks in the AddTracks merge. Clarify that the playlist listing omits unknown durations (browser already hides them) and still walks directory sources to count files.
|
Resolution for the two walkthrough findings that could not be posted inline (review of fcc144f):
|
dirSuppliesFile now validates the candidate extension against player.SupportedExts before the path-containment checks, so non-audio files added as explicit tracks (e.g. cover.jpg under a [[dir]]) are appended at the end instead of being inserted before the directory section.
- Normalize ExpandPath's env-expanded result with filepath.Clean before comparing: on Windows the raw expansion mixes / and \ separators. - Assert TestSavePlaylistPreservesDirsAndSkipsDirTracks against the parsed document instead of raw text: the writer escapes backslashes via %q, so substring matching of a Windows temp path never matched.
- p now opens the playlist manager from any source pane, not just the songs view - a on the manager list creates a playlist and drops into the file browser at ~ targeted at it; Space selects folders and/or files, Enter descends or confirms, Esc acts as done and commits anything pending - selected folders become [[dir]] sources, selected files become explicit tracks (builds on bjarneo#308) - r renames and d deletes playlists with y/n confirm; Recently Played cannot be renamed or deleted - provider pane re-pulls counts after creation and after every write so dirs/tracks/duration match other playlists immediately - creating no longer auto-adds the currently playing track

Dynamic directory playlists via
[[dir]]sourcesProblem
Local TOML playlists hardcode every track as a
[[track]]entry. Pointing a playlist at a music library like~/Musicmeans writing hundreds of lines to the file, and the playlist goes stale the moment a file is added, renamed, or removed.What this adds
A playlist file can now reference a directory that is scanned for audio files every time the playlist loads, instead of listing each file:
Only 4 lines to reference an entire library. New files show up automatically, removed files disappear — no editing needed.
How to use it
CLI
Manual TOML
Where the files live: playlists are plain
.tomlfiles in the config directory'splaylists/subfolder — the filename (minus extension) becomes the playlist name, so every non-directory.tomlfile in the folder is picked up automatically, CLI-created or hand-written (files that fail to parse are skipped):(The folder is created automatically on first use. It follows cliamp's config-dir resolution:
CLIAMP_CONFIG_DIR, thenXDG_CONFIG_HOME/cliamp, thenHOME/.config/cliamp.)Users can keep one file per collection and mix hand-written and CLI-created files freely. One playlist file can hold any number of
